John:

Let me think about it for a bit. Can you define "BUNCH" for me? How to
approach this will depend to a certain extent on the potential numbers
involved (i.e., one-off vs production).

(As an aside, we designed a custom prop for one of the mid-90's AC
syndicates to use in side-by-side testing. They wanted to match drag
figures
as closely as possible, so they were looking to add some 30-35 lbs
thrust to
one hull. The existing trolling motor props lost all of their thrust as
boat
speed increased, so we did a prop with much higher pitch to get a better
speed-rpm-pitch match where they needed to be. Who knows, there might be
a
nice market for replacement props with higher pitch for small boats.)

YES! There is definitely a small but viable market! There are a BUNCH of
us
with 21' SeaPearl sailboats who use various electric motors as
auxiliaries. I
am almost positive I could get significantly more speed with a
higher-pitched
prop, but have found nobody who makes one. Any chance of getting one made
for a
MinnKota EX42 for a trial?

I would guess initially a dozen who might take an exploratory plunge, with a few
dozen possibilities after that.

I've copied this to our e-mail group, so I might get a better idea of immediate
interest.

Pearlers: How many might be interested in a source for a high-pitch prop for
the electric motors on their SeaPearls?
